Welcome to my nightmare

I think my greatest fear is having to hide for my life. I was introduced to world war two and the horrors that the Nazi committed against the Jewish people at a very young age and I think that may have traumatized me a bit. My worst nightmare is connected to this fear. I had just seen the movie "War of the Worlds" maybe a week before I had this dream and I think it triggered my fear and caused the nightmare. It is kind of interesting that it was this movie in particular because I never really found the actual movie scary, but in my nightmare it was the scariest thing I ever had to experience. There is a scene in the movie where the protagonist family is hiding from the alien machines in a basemen and all is quiet. The machine sends a thing that looks like an eye but is the size of one of those big beach balls that people throw around in baseball games. It is this scene in particular that most resembles my nightmare. In my nightmare, I and four other kids who I did not know were all hiding together. I remember feeling like I could not breathe because I was afraid it would give us away. I was not afraid of dying after being found, but rather, I was afraid of being discovered. It was like being found by them meant something worse than death. An irrational fear I suppose, but a fear nonetheless.
